(2013-02-12)Protein interactions that take place at the interface of a membrane are abundant within cellular organisms. Hence, surface coupled protein interactions are a matter of ongoing scientific investigation. In this work, elected ... -
Indole Alkaloids as Potential Leads in Drug Discovery and Further Secondary Metabolites from Terrestrial and Marine Bacteria
(2012-01-04)Microorganisms take a large influence on ecological and symbiotic interactions in long-term relationships that are moderated by secondary metabolites with often-unique structure and biological ... -
Inelastic H-Atom scattering from ultra-thin films
(2018-09-05)This thesis contains experimental and theoretical fundamental studies of energy transfer processes on various surfaces via inelastic hydrogen atom scattering using the Rydberg atom tagging machine. The initial investigations ... -
Inelastic Hydrogen Atom Scattering from Semiconductor Surfaces
(2023-12-11)The adiabatic approximation is widely applied to describe interactions of atoms and molecules with solid surfaces. It assumes that the electronic system stays in the lowest-energy ground state during the interaction and ... -
Influence of ezrin's actin binding properties on the formation of minimal actin cortices
(2024-02-16)The cytoskeleton is a pivotal structure within cells, crucial for their motion and life-indispensable processes. The actin cortex is a dense actin network that is part of the cytoskeleton and linked to the plasmamembrane. ... -
Influence of point mutations on the electrophysiological properties of a bacterial porin and its interaction with a β-lactam antibiotic
(2018-09-19)The high rate of complications and mortality in hospitals due to multidrug resistances (MDR) of gram-negative bacteria demonstrates the urgency to understand the underlying mecha-nisms. One common cause of MDR are mutations ... -
Initiierungseffektivität von linearen und zyklischen Dialkylperoxiden in der Ethen-Hochdruckpolymerisation
(2001-06-29)Transfer constants in ethene homo-polymerization for two aldehydes and one ketone were determined using the mayo-method and the chain-length-distribution method. Various peroxides were used ... -
Integration von Connexonen in Lipidmembranen auf porösen Oberflächen
(2010-08-18)Connexin26 (Cx26) is a member of the connexin family, the building blocks for gap junction intercellular channels. These dodecameric assemblies are involved in gap junction-mediated ... -
Interaction of antimicrobial compounds with lipid bilayers in established and novel membrane model systems
(2021-05-06)Investigating the interaction between antimicrobial compounds and membrane model systems in the form of artificial lipid bilayers provides important insights into their mode of action. The interaction of lipid side chains ... -
Interaction of he Epsin N-Terminal Homology domain (ENTH) with artificial membranes as a function of lateral tension
(2016-09-01)During endocytosis, membrane remodeling of a planar membrane into a highly curved vesicle is controlled by a complex protein machinery. However, the regulatory role of physical properties such as membrane tension is ... -
Intermolecular energy scales based on aromatic ethers and alcohols
